Simultaneous determination of chlorothalonil and its metabolite 4-hydroxychlorothalonil in greenhouse air: Dissipation process of chlorothalonil

Chemosphere, 2008
An analytical method was developed and tested for the simultaneous determination of chlorothalonil and its main metabolite 4-hydroxychlorothalonil, in airborne samples. High performance liquid chromatography equipped with Ultra-violet detector was used to separate and quantify the analytes.

Regulation of chlorothalonil degradation by molecular hydrogen

Journal of Hazardous Materials, 2022
Pesticides can accumulate throughout the food chain to potentially endanger human health. Although molecular hydrogen (H2) is widely used in industry and medicine, its application in agriculture is just beginning. This study showed that H2 enhances the degradation of the fungicide chlorothalonil (CHT) in plants, but does not reduce its antifungal ...

Hydrolytic Dechlorination of Chlorothalonil by Ochrobactrum sp. CTN-11 Isolated from a Chlorothalonil-Contaminated Soil

Current Microbiology, 2010
A bacterial strain, designated as CTN-11, capable of degrading chlorothalonil (CTN), was isolated from a chlorothalonil-contaminated soil in China. Based on the morphological, biochemical characteristics and comparative analysis of the 16S rRNA genes, strain CTN-11 was identified as Ochrobactrum sp.

Reaction of diazomethane with chlorothalonil

Chemosphere, 1983
Abstract The reaction between diazomethane and chlorothalonil produced a major compound identified as 4-methoxy-2,5,6-trichloroisophthalonitrile. The latter compound was also produced by methylating the 4-hydroxy derivative of chlorothalonil with diazomethane. It is suggested that derivatization of the hydroxy metabolite of chlorothalonil in presence

Glutathione-Dependent Biotransformation of the Fungicide Chlorothalonil

Journal of Agricultural and Food Chemistry, 2004
A gene responsible for the chlorothalonil biotransformation was cloned from the chromosomal DNA of Ochrobactrum anthropi SH35B, capable of efficiently dissipating the chlorothalonil. The gene encoding glutathione S-transferase (GST) of O. anthropi SH35B was expressed in Escherichia coli, and the GST was subsequently purified by affinity chromatography.

Recent Advances in the Biodegradation of Chlorothalonil

Current Microbiology, 2011
Chlorothalonil (TPN; 2,4,5,6-tetrachloroisophthalonitrile) has been widely used as a broad-spectrum chlorinated aromatic fungicide and its application resulted in global pollution commonly detected in the diverse ecosystems. Recently, microbial degradation of TPN has been studied extensively as an effective and environmental-friendly method to reduce ...

Embryotoxicity of oral administered chlorothalonil in mice

Birth Defects Research Part B: Developmental and Reproductive Toxicology, 2006
AbstractBACKGROUND: Chlorothalonil (2,4,5,6‐tetrachloroisophthalonitril), the nephrotoxic fungicide, was examined for its potential to produce developmental toxicity in mice after oral administration. METHODS: Pregnant ICR (CD‐1) mice were given sublethal doses of 0 (corn oil), 100, 400, and 600 mg/kg/day chlorothalonil by gavage on gestation days (GD)

Photodecomposition of chlorothalonil in benzene

Pesticide Science, 1983
AbstractChlorothalonil (2,4,5,6‐tetrachloroisophthalonitrile) in benzene was photodecomposed by sunlight or low energy ultraviolet irradiation to a monophenyl adduct identified as 3,5,6‐trichlorobiphenyl‐2,4‐dicarbonitrile. However, irradiation with a 100‐W high‐energy ultraviolet lamp yielded an additional compound identified as 2′, 5′ ‐dichloro‐m ...

Chlorothalonil: lack of genotoxic potential

Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1999
Based upon analyses using a number of validated structure-activity relationship models, it is concluded that the carcinogenicity in rodents of chlorothalonil is not due to a genotoxic mechanism.
